UNITED STATES PATENT OFFICE.

To all whom it may concern:

Be it known that I, JOHN A. HAnms, a

citizen of the United States, residing at Los Angeles, Los Angeles County, California, have invented a certain new and useful Garage Double-Door Operator and Fastener, of which the following is a specification.

An object of this invention is to make a combination, with a garage door having two sections mounted to swing to and from each other, of means connecting the two sections together for simultaneous opening, closing, locking and unlocking, and latching and unlatching, by manipulating a single handle.

Other objects and advantages may appear from the drawings and specification.

Fig. 9 is a view analogous to Fig. 2 and showing a modified construction.

Fig. 10 is a view analogous to Fig. 3.

Fig. 11 is an enlarged fragmentary plan of the mechanism at the rear ends of the links in Fig. 9.

Fig. 12 is a fragmentary view partly in section and as indicated by the arrow 12 in Fig. 11.

The details of construction and operation shown in the drawings are as follows.

The garage enclosure 1 has a door open ing 2 with the door frames 3 and 4. The door section. and (i are connected to the frames and 1 respectively by hinges 7 and 8 and swing together until their edges meet on the line 0 when closed and swing away from each other outwardly when open. A hasp 10 is mounted upon the door section 5 and engages a staple 11 to which a lock 12 may be applied to lock the door sections closed. The hasp 10 serves as a handle.

Adjustable operating links 1? and 14 are connected to blocks 15 and 16 secured to the inner sides of the sections and 6 by L shaped pivot bolts 17 and 18 at the 't'orward end of the links, and the. rear ends of the links 13 and 14 are pivotally connected to gether by plates it) and 20 and rivets 21 and 29 fixed through the plates and links.

Fiach link if) and 14 is adjustable in length as shown in Fig. 8. An eye 2:? fits a block 24 and the block and eye lit in one end of the casing 25 and are held by rivets 26. A stick 27 telescopes into the other end of the casing 25 and is held in adjusted position by bolts 28, there being a plurality of bolt holes 29 in the casing. The eye 23 fits the vertical portion 30 of the bolt 17 An adjustable guide arm 31 is rigidly se cured between the plates 19 and 20 by rivets 32 and 33, and consists of a stick 34 connected to a pipe 35 by U-bolts 36 and 37, so that the length may be adjusted. An elbow 38 is connected to the pipe 35 and a second pipe 39 is connected to the elbow and extends downwardly through bearings 40 and 41 secured to the rigid frame 42, so that the arm 31 may swing on a vertical axis and guide the connected rear ends of the links 1 and 14.

A double-ended spring catch 43 is pivotally mounted upon the rivet 22 and is held yieldingly in latching position by a spring 44. The catch 43 has a bevelled rear end leading to a notch 45, so that when the door is closed the catch will sna J into engagement with a pin 46 held rigid y and extending downwardly from a frame bar 47 and hold the door closed. The pin 46 engages in the notch 45. The catch has a bevelled front end 47 leading to a notch 48, so that when the door is opened the catch will snap into engagement with a pin 49 extending downwardly from a frame bar 50. The pin 49 engages in the notch 48.

A chain 51 is connected to the catch 43 in front of the rivet 22 and passes back of the rivet 21 and forwardly along the link 13 and is connected to one end of the bell-crank lever 52, and a second chain 53 is connected to the other end of the lever 52 and extends downwardly and is connected to one end of a second bell-crank lever 54, and a third chain 55 is connected to the other end of the lever 54. An extension lever 56 is welded to the hasp 10 and extends through an opening 57 in the door section 5 and is connected to the chain 55, so that when the hasp 10 is used as a handle swung outwardly from the door catch 43 is operated to release the catch from o and 6 so that they may be opened or closed.

he mechanism for connecting and operating the door sections is all overhead so that vehicles may readily pass into and out of the garage without danger of colliding with the mechanism and the hasp or handle 10 is in convenient position for manual manipulation.

The links 13 and 14 and guide arm 31 may be adjusted and located to swing the door sections 5 and 6 to any desired open positions, or to swing either one to a different open position than the other, as desired.

The details of the modified construction shown in Figs. 9, 10, 11 and 12 are as follows:

The swingin guide arm 60 is connected to the frame 61 %y a vertical link 63 is connected to the free end of the guide arm by a hinge 64. The link 65 is connected to the guide arm by a hinge 66. The double ended mounted upon a bolt 68 extending through the end of the guid retractile coil spring 69 connects the rear end of the catch 67 to the guide crank lever 70 is mounted upon a bolt 71 extending vertically through the guide arm and a link 72 connects the forward end of the bell-crank lever to the forward end of the catch 67. A chain 73 is connected to the rear end of the bell-crank lever 76 and extends along the link 63 and is connected to the chain 74 in the same manner as the preferred form.

The catch 67 has a rear notch 75 and a rear bevelled end 76 and has a front not-ch 7'7 and a front bevelled cud 7'8, to engage the pins 79 and 86 respectively, the same'as in the preferred form.

A lever 81 is pivoted to extend through the opening 82 in the door section 83 and has its inner end connected to the chain 74 and has an outer end 84 in position to be engaged by the hasp 85 when the hasp is used as a handle.

The forward ends of the links 63 and 65 are hinged to blocks 86 and 87 secured to the door sections 83 and 88. The guide arm 64 and the links 63 and 65 are cut to fit and give the door sections 83 and 88 the desired swing. The meeting edges 89 and 90 of the door sections are rahbeted and the door sec- 88 is set to close slightly ahead of the door section 83 so that the edges will not jam. The operation is practically the same as the preferred form.

Various changes may be made without departing from the spirit of the invention as claimed.

I claim:

1. A garage door comprising two door sections mounted to swing to and from each other, links pivotaly connected at the tops of the door sections and extending inwardly and pivotally connected together at their rear ends, a guide arm mounted to swing on a vertical axis and connected to the rear ends of the links, a spring pressed double catch at the rear ends of the links, there being a rigid pin to be engaged by the catch and hold the door sections closed and there being a second rigid pin to be engaged by the catch and hold the dor sections open, a hasp on one of the door sections to serve as a handle, and a connection between the hasp and the catch for releasing the catch from the pins to move the door sections.
